Opt lasers or Jtech

I am looking to take the plunge into a laser for my cnc. Optlasers seems to have a decent deal on right now for for their Onefinity cnc kit (free u-spot lens and air assist nozzle), but doesn’t have any support from Onefinity themselves, which seems reasonable since its a 3rd party accessory. Or I can order the J-tech laser straight from Onefinity, I am in Canada so this is the all around easier option. The price difference would be around $300 more to go with the Optlasers but again seems to include more accessories and a better build quality.

I am looking for some feedback from anyone who has used either. My use for it would be for engraving wood and I am hoping to cut 3mm or less plywood occasionally with it.

One thing to keep in mind, we only sell and support the jtech laser, so if there an issue with another brand, you’d be reliant on the community for assistance.

Thanks so much for bringing this sale to our attention. Those discounts amount to about 1/3 off. What a bargain. Shipping all the way from Poland is $33. My order is in!


I have the Opt Lasers with µSpot and air assist nozzle and I’m very pleased with it. I published my first impressions a while ago. With more experience, what I like:

  • material and build quality, mostly metal
  • safe: the laser detaches itself and turn itself off it you crash the head in the board. No arm to the laser or… to you!
  • air nozzle makes for very clean engraving/cuts, particularly if you place an honeycomb under the board to cut
  • they ship from EU, so no problems with VAT/import fees

I have had no problems engraving and, after fine tuning my settings, I can cut 3mm ply in one pass. I use Lightburn and Fusion 360. A recent project.


Curious: What can you engraver with the laser? Are they able to engrave fine detail in metal (Al or Ag) or is it limited to wood and plastics

Thanks for the feedback Ben, I had reviewed your first impressions post earlier and your pumpkin boxes look amazing, I am pretty sure that I am going to go ahead and order the Opt lasers kit, it just seems like a better overall value. I may need to pick your brain once it arrives, what kind of pump did you get for the air assist?

I have only done wood but Opt Lasers claims that they can engrave metal. I tried Delrin and the laser has no effect at all.

I plugged it into my compressor, via a pneumatic push in connector, which I run at very low pressure.
Reportedly you can use an aquarium pump (you really don’t need a lot of pressure) but the compressor is close to the CNC so I had no need to buy a new pump.

Steel is demonstrated and impressive and the detail on some of the examples look fantastic.

Now I’m interested but feel that I should concentrate on what I have - I fancy the metal/silver engraving

Just some purchase info for anyone else looking at the Opt Laser - I decided to go for the PLH3D-6W-XF+ Opt Laser Onefinity kit. Their current ‘Black November’ promo included: Free µSpot Lens & Air Assist Nozzle - these we’re basically the deciding factor for me over Jtech. I added a couple of backup cables to my order ($5/USD ea), and shipping to Canada was $33USD.

After the conversion to CAD$ - the kit costs a couple dollars under $1200 CAD.


I would choose opt lasers only because of the overall quality feeling compared to Jtech and also because of the fact that you can get different lenses to the laser module as well as high pressure air assist nozzles etc.

I have not owned Jtech. I was thinking about buying it when i started to look into diode lasers but quite fast i found opt lasers and i was sold to them.

An i can really recommend Opt Lasers. The quality is really good as well as the support. I have owned it for over 1.5 years now with no problems till this day.

A real nice dimond for around 1k€. :ok_hand: :+1: :gem:
